ventilation device

Abstract

The invention relates to an exhaust device. The exhaust device comprises a discharging frame, a connector frame which is arranged on one side of the discharging frame, a first filter plate which is arranged on the inner side surface of the discharging frame, a second filter plate which is arranged in the connector frame and an exhaust device body which is connected to the connector frame, wherein the discharging frame is arranged below a laser cutting platform and forms a closed cavity with the laser cutting platform, the first filter plate is covered above a window, a plurality of first projections which are arranged in an array manner are convexly arranged on the first filter plate, a first vent hole which passes from bottom to top and then inwards penetrates through each first projection is formed in the lower end surface of the first projection, a second vent hole which passes from top to bottom and then inwards penetrates the second filter plate is formed in the upper end surface of the second filter plate, and the direction of each first vent hole is opposite to that of the second vent hole. The second filter plate is arranged in the connector frame, so that waste material can be prevented from falling into the exhaust device body not to damage the exhaust device body while the exhaust effect is guaranteed.

Description

technical field [0001] The invention relates to a laser processing device, in particular to a ventilation device for sucking smoke generated during laser processing. Background technique [0002] Toxic and harmful gases are easily produced during laser processing, which affects the company's environment and the personal safety of operators, and the smoke generated by source light processing affects the quality of subsequent product processing, making the product surface easy to yellow and burn. If the processed waste is sucked into the exhaust duct, it will cause the exhaust duct to catch fire and cause property loss of the company. Therefore, the cleaning of laser processing waste gas has become an urgent problem in the existing laser processing field. [0003] In order to clean up the harmful gas generated during laser processing in time, the existing laser processing equipment is generally equipped with a ventilation system; however, the design of the ventilation outlet o...

Problems solved by technology

[0002] Toxic and harmful gases are easily produced during laser processing, which affects the company's environment and the personal safety of operators, and the smoke generated by source light processing affects the quality of subsequent product processing, making the product surface prone to yellowing and burning

If the processed waste is sucked into the exhaust duct, it will cause the exhaust duct to catch fire, resulting in property loss of the company. Therefore, the cleaning of laser processing waste gas has become an urgent problem in the existing laser processing field.

[0003] In order to clean up the harmful gas generated during laser processing in time, the existing laser processing equipment is generally equipped with a ventilation system; however, the design of the ventilation outlet of the ventilation system in the existing laser equipment is unreasonable, so that the waste is easily sucked into the ventilation duct , affect the ventilation effect, and there is also the problem that the ventilation outlet is easy to be blocked, causing the harmful gas to be discharged cannot be discharged in time, and it needs to be cleaned frequently
